Polyphenol Nanoformulations with Potential Antidiabetic Properties

Abstract

The physiochemical stability of polyphenols is affected by environmental parameters (e.g., light, oxygen, or temperature) and hence their metabolism, stability inside the biological system, bioavailability, and bioactivity are altered. These limitations can be overcome by loading the polyphenols into nanoparticles. An increase in the bioavailability of polyphenol (epigallocatechin gallate, curcumin, and resveratrol) nanoparticles is observed with an enhancement in their solubility, prevention of intestinal environment-mediated degradation, elevation of the permeation rate in small intestine, and enhancement of its pharmacokinetic characters. The bioactivities such as anticancer, antioxidant, antidiabetic, and anti-inflammatory of polyphenols have been reported to be enhanced after nanoparticle encapsulation.
